Overall: A weaker version of Blue Gender, but with a great OST. I'm giving 4 stars on the OST alone. So it is at least worth watching just to hear the OST. The animation looked like one of the Saint Seiya reboots, which I don't like, but the production value was good. If Yakitori does anything else good, it is negligible, because the rest is so basic. A total of 4.5 stars max. Is the story unique? If it was predictable, did you enjoy it anyway because you like this genre/set-up? Story was completely predictable with just one small plot twist on thefinal episode, but it doesn't try to answer any big philosophical questions.

Do you think the art style is fitting for the story?
No, needed a different method of doing the CGI.

Were the characters well-rounded? Did they have flaws and strengths, or were they unusually strong/smart/stupid?
Just terrible stock characters. I remember when people were mad about Akudama Drive about this (excluding Swindler), but at least Akudama Drive had a flare to its' artwork and story direction had style points.

Did the characters react to situations and events in a realistic way?
The characters reacted to everything in such a predictable and vanilla way.

Do you think others will enjoy/dislike this series, even if you didn't? Why?
Someone who is new to anime might like this or someone studying to read, listen, and speak Japanese for some practice. It is way too vanilla for anime vets. Music geeks will rejoice.
